Title: A simple optical system for real-time size measurements of TRISO fuel pellets

Abstract

Oak Ridge National Laboratory (ORNL) has begun the development of a program for the manufacturing and characterizing fuel pellets for use in advanced nuclear reactors. To achieve high reliability it is necessary to characterize the pellets during production runs. In this paper we present a simple TRISO Particle Counting And Sizing Tool (TP-CAST) that performs dual measurements of counting and size estimation for particles at rates up to 200 per second. The TP-CAST is based on a laser with line-generation optics and a PC-based data acquisition and analysis system. The instrument can measure 1000 micron pellets with a standard deviation of approximately 11 microns and with counting errors less than 0.075%. Our paper discusses the signal modeling, algorithms for size estimation, system design, and experimental results of the prototype TP-CAST system assembled at ORNL.

  • The aethalometer is an instrument that responds to the concentration of aerosol black carbon in real time. Recent versions constructed at Lawerence Berkeley Laboratory (LBL) contain two or three channels that may be operated simultaneously. When preceded by size-segregating inlets of differing cut points, this configuration allows for a real-time determination of the size fractionation of the black carbon component of the aerosol. In field measuremens at LBL, we studied the incorporation of black carbon into marine fog droplets by comparing the total concentration with the ''interstitial aerosol'' concentration measured downstream of an interception mesh of 1-..mu..m cutpoint. The datamore » show that up to 80% of the carbon may be occluded by dropplets. In separate experiments during SCAQS program in southern California, a three-channel instrument, equipped with impactors, measured total, <1 ..mu..m, and <0.03 ..mu..m concentrations, and showed duirnal variations of size fractionation of the ambient carnonaceous aerosol. These results imply that a significant fraction of the aerosol black carbon particles may exhibit hygroscopic behavior. 6 refs., 3 figs.« less
  • The authors present an apparatus capable of detecting micron sized particles traveling at speeds up to 10{sup 6} cm/sec. The apparatus uses light scattering methods with automated data processing. Data generated by this apparatus should be extremely useful in radiation damage studies of components in contamination sensitive optical systems.
  • This paper presents a brief description and discussion of the results of a reduced size computer program for long-term power system simulation. It includes detailed models of a hydro, a coal-fired and a pressurized water reactor (PWR) generation plant. Typical data taken from operating records have been used. Since the simulation runs faster then real-time, the program can be used as a power system simulator operator training.
  • The approximate solution to the equation of transfer for optical radiation in the atmosphere above the sea is obtained. For a zeroth approximation derivation of the equation of transfer, a bi-transport representation of the light scattering phase function was used. Already in this approximation an equation for the transmittance of the atmosphere is obtained within an accuracy of about 5%. The next approximation leads to expressions for radiance factors of the sky and ocean-atmospheric-layer system, the latter of which, in the case of an homogeneous atmosphere and not very oblique sensing and solar angles, transforms at the upper boundary ofmore » the atmosphere into the well-known formulae used for processing optical satellite data. The results of this study can be used to develop algorithms for processing airborne and shipborne optical information. 5 refs.« less
